BELTING OR WEBBING.

Specification of Letters Fatent.

Patented Mar. 27, i917..

Application filed September 11, 1915. Serial No. 50,283.

yTo all whom t may concern:

'Britaim residing in Barry, Wales, have invented certain new `and useful Improvements in Belting or VVebbing, of which the following is a specification.

This invention relates to a new or improved textile or like fabric or webbing, and is designed to provide a fabric in which the edges are protected by a plaited rim or selvage adapted to take any rubbing or wear to which the edges may be subjected and so prolong the life of the material.

'The invention provides a fabric or Webbing which may be substituted for leather straps or belts or may be used for other purposes Where the edges of the fabric are apt to be rubbed or worn. It is for instance particularly applicable for the manufacture of belting for driving machinery, and the like, in which case the plaited rim or selvage may be formed of a strong or tough material secured in such a manner that the friction or Wear of belt forks, flanged pulleys or other rubbing or wearing surfaces is taken thereby in such' a manner that the main material of the belt is not worn and spoiled by it, the life of the belt being in this manner much increased.

It has previously been proposed to make a multiple-ply fabric, suitable for belting, having a rim or selvage of strands of leather, cord or other suitable material twisted together and secured to the edge of the fabric by the weft as the fabric is woven, and woven and similar belts having selvages of plaited fibers attached by sewing have also been proposed and this application makes no claim to such arrangements.

The invention consists essentially of a multiple-ply fabric having a rim or selvage of strands of suitable material plaited together, such rim or selvage being secured or attached to the edges of the fabric by the weft as the fabric is woven.

The plaited rim or selvage may be formed of the same material as the body of the fabric, or it may be formed of'stronger or tougher material. For machine belting, for instance, it may be formed of strands of leather, cord, thin rope, fiber or other strong or tough material.

In carrying out the invention, the improved rim or selvage is preferably formed of three or more strands of the material chosen, the strands being plaited together in such a manner that each strand in turn serves to lock or secure the adjacent strands in the manner of an ordinary plait. One or two strands of material may also be employed plaited on itself or themselves in such a way as to form a multiple and interlocking` plait or the like. i

Such a plaited rim or selvage may be attached to the edges of the fabric in any suitable manner by the weft in the process of weaving v rllhe plaiting of the rim or selvage preferably takes place as the fabric is woven and the separate strands are caught up by the weft in the process of weaving. This preferably does not take place at every pick, but at every few picks and the plaiting of the rim or selvage strands takes place in such a manner that the parts of the strand caught up by the weft are covered over by adjacent strands, so that nowhere do the securing portions of weft come to the outside of the rim, but are protected by the exterior portions of the plait which take up all the rubbing or friction against the edge, such as is caused in machine belting, for instance by belt forks, flanges, or the like.

Alternate strands ofthe plait caught up by the weft are also preferably arranged to lie at opposite angles against the edge of the woven part of the belting so that the weft atv the alternate places where it crosses and secures the strands also lies at opposite angles. This assists to secure the plaited rim tightly against the edge of the fabric.

rlhe invention will be fully described with reference to the accompanying drawings.

Figure 1 is a perspective View of a piece of webbing made according to the invention; Fig. 2 is a perspective view of a piece of belting made according to the invention, and Fig. 3 is a side view of the belting, parts being in section.

The body of the fabric or belt A may be of any suitable or desired multiple-ply weave and one or both edges are provided with a plaited rim B. In construction, the plait is formed as the fabric or belt is woven, and each strand b of the plait as it is laid against the edge of the fabric or belting is caught up by the weft C as the shuttle is thrown backward and forward in the loom. As the plaiting proceeds, the adjacent strands cover over the weft loops C so that when the fabric or belting is in use, these loops are prothe loops of the weft being covered and protected by strands of the plaited portion.

2. A `fabric comprising' a multiple ply Woven portion and a plurality of plaited portions united to said Woven portion by the weft' thereof, the loops of the weft being covered and protected by strands of the plaited portion.

' 3. A fabric comprising' a multiple ply woven portion and a rim or selvage of plaited strands secured or attachedto the edge of said Woven portion by the weft thereof, the loops of the weft being covered and protected by strands ofthe pla-ited portion.

4. A belting comprising a main Woven portion and a plaited rim portion secured to the edge of the belting by the weft, the loops of the weft being covered and protected by strands of the plaited portion.

5. Woven belting or the like having a rim composed of strands of relatively tough lnaterial plaited together and secured to the edge of the belting by the weft, the loops of the weft being covered and protected by the strands of said plaited portion.

6. Belting comprising a main Woven portion and a plaited rim portion in which each strand of said plaited portion is secured to the Woven portion by the weft at those places Where it lies against said Woven portion and is covered by another strand of said plait.

ln testimony whereof I have signed my naine to this specification in the presence of two subscribing Witnesses.
